danny0405 opened a new pull request #10523: [FLINK-15073][sql-client] SQL-CLI 
fails to run same query multiple times
URL: https://github.com/apache/flink/pull/10523
 
 
   ## What is the purpose of the change
   
   After we change the SQL-CLI to stateful in FLINK-14672, each query's
   temporal table was left out so we can not re-registered the same
   object(from the same query).
   
   ## Brief change log
   
     - Remove the temporal table registered after the query was executed
     - Add test cases for same query re-execution
   
   
   ## Verifying this change
   
   See tests in LocalExecutorITCase.
